摘要: We present a novel mid-IR source based on optical parametric chirped pulse amplification (OPCPA) generating 96 fs pulses (9.0 cycles) at 3.2 μm with an energy of 1.2 μJ, repetition rate 100 kHz. The amplified spectrum supports minimum Fourier transform limited duration 45 fs, or 4.2 cycles. Our use OPCPA allows the direct few-cycle this wavelength, and is inherently scalable to higher energies. seed for system difference frequency generation (DFG) between two outputs same fibre laser: expected be intrinsically CEP stable.
